What Causes Coughing Mucus and Phlegm?
A cough that is accompanied with mucus or phlegm (sputum), commonly called a "productive cough," is usually a sign that an infection has developed in the lungs. Coughing up phlegm or mucus can be caused by various things and include the common cold, allergies, irritants (smoking, dust, pet dander, chemical fumes), gastro-esophageal reflux or bacterial or viral infections in the lungs such as acute bronchitis, pneumonia, whooping cough, croup in children. The mucus or phlegm often varies in consistency and color ranging from yellow, green, brown, grey or may even contain blood.
Coughing mucus and phlegm commonly occurs in the morning. If you are coughing up mucus and phlegm and it persists, consult your doctor. Constantly coughing mucus and phlegm can lead to nausea. Based on your cough symptoms, your doctor will perform a physical examination as well as certain diagnostic tests. Tests such as a chest x-ray, blood tests, sputum examination, ECG and CT exam may be ordered to rule out serious diseases such as TB or lung cancer.

Productive Coughs in Babies and Children
A common cold virus is usually responsible for causing coughing in children and babies, and a 'heavy' type of cough is often caused by mucus and phlegm running down the nose and into the chest.
To help your child have a more productive cough, give them some steam. For very young children and infants, take them into the bathroom and sit in the hot steam for 10-15 minutes. Older children can benefit from using a warm steam vaporizer, as well as blowing their nose several times during a steam treatment.
Position infants and children into an upright sleeping position, allowing for easier breathing during sleep. Also be sure that they drink plenty of liquid, which helps to thin secretions as well as prevent dehydration.
Coughing, Mucus and Phlegm During Pregnancy
Nasal congestion, coughing and phlegm are very common symptoms experienced during pregnancy. Fluctuating hormone levels and estrogen are known to exacerbate mucus production and can cause the mucus to get very thick or thin.
Self-care is usually the best approach for handling these issues. Avoid environmental irritants as much as possible, such as pet dander and cigarette smoke. Be sure to stay hydrated, and avoid caffeinated beverages, which can lead to dehydration. Sleep with your head elevated, and use a warm steam vaporizer to help make coughs more productive.
Help for Coughing Mucus and Phlegm
Treatment of a persistent cough and phlegm involves using a good cough mixture recommended by your pharmacist or prescribed by your doctor. Avoid using over-the-counter cough suppressants as they may not be the most suitable product. Expectorants and mucolytics may be prescribed to break up mucus and phlegm thereby making it easier to cough up.
Do not combine an expectorant with an antihistamine, decongestant or cough suppressant as they may bring about negative side effects. Breathing steam from a hot shower or vaporizer has also shown to be quite effective in loosening mucus and phlegm and keeping the airways moist.
Foods to Help Break Up or Loosen Mucus and Phlegm
Certain fruits such as pineapple, oranges, grapefruits, and lemon have been shown to have beneficial effects on breaking up mucus. As far as veggies, asparagus, onions, cauliflower, celery and garlic can help eliminate mucus.
Also, avoid cold foods when suffering from excessive mucus and instead choose warmed foods, which help thin and open airways to allow for easier mucus elimination. Herbal teas are especially helpful , as are spicy foods, such as those made with hot chili peppers or horse radish.
Natural and holistic treatments have been used for centuries to treat various respiratory conditions. Homeopathic remedies are a safe and effective alternative for people of all ages and encourage the body’s healing response quickly. Carefully selected ingredients such as Kali mur, Kali sulph and Kali bich helps to control mucus production, soothes a clogged up chest and relieves coughing episodes without the risk of addiction or side effects.
